Hi Blane,
You could do something like:
var mapDiv = document.getElementById('map-div-id');
var map = new google.maps.Map(mapDiv, myOptions);
mapDiv.map = map;
then later you can get the map by doing:
document.getElementById('map-div-id').map
I'm just writing this off the top of my head so it might not work in all
browsers.
